We were gonna go last year when we spent a week at Durango but didnt end up happening.
The 2 tips I got from the locals about it though were:
1) MAKE SURE THERE IS GOOD SNOW
2) If you are an advanced rider, get a group of 4 riders with similar ability and ditch the guide! Ive heard a lot of people complain about how their guide couldnt keep up with them.
Definitely a place on my list to hit so make sure you put some pics/vids up if you go
